以下是notify.php中的异步通知处理

/**** @desc:支付宝支付结果同步回调*/public function alipayReturn(){$param = $this->request->param();$result = $this->dealNotify($param,false,1);if($result['state']){//支付成功$this->redirect(url('index/buy/payok',['pay_sn'=>$param['out_trade_no']]));}else{//支付失败$this->redirect(url(''));}}/*** @param unknown $data* @param boolean $sign 是否验签* @param boolean $type 1-同步处理 2-异步处理* @desc:处理支付宝同步通知和异步通知数据*/private function dealNotify($data,$sign = false,$type = '2'){try {$typeDesc = ($type == 1)?'return':'notify';$prefix = 'alipay-'.$typeDesc;$alipay = new Alipay();$alipay->setLog($data,$prefix."-param:");//1-alipay数据验证$result = $alipay->notify($data,$sign);if(!$result['state']) throw new Exception($result['msg']);//2-检测支付金额是否一致$pay = new Pay();$result = $pay->checkPayTotal($data['out_trade_no'], $data['total_amount']);$alipay->setLog('账单实际金额:'.$result['data']['total'].",实际支付金额:".$data['total_amount']);if(!$result['state']) throw new Exception($result['msg']);//修改订单相关数据$this->purOrderUpdate($data['out_trade_no'], $data['trade_no'],$data['total_amount']);$alipay->setLog('success',$prefix."-end:");return callback(true);} catch (Exception $e) {$alipay->setLog($e->getMessage(),$prefix."-end-error:");return callback(false,$e->getMessage());}}/*** * @desc:支付宝支付结果异步回调(包括部分退款异步通知。全额退款没有异步通知)*/public function alipayNotify(){try {if(!$this->request->isPost()) throw new Exception('非法请求');$param = $this->request->param();if(isset($param['refund_fee'])){$alipay = new Alipay();$alipay->setLog($param,'refund-notify:param:');//退款状态修改$this->_updateRefund($param['out_biz_no'],1);$alipay->setLog('success','refund-notify-end:');}else{//支付结果异步通知$result = $this->dealNotify($param);if(!$result['state']) throw new Exception($result['msg']);}return 'success';} catch (Exception $e) {$alipay->setLog($e->getMessage(),'notify-end-error:');return 'fail';}}

注意：申请退款后，部分退款才会有异步通知,全额退款不会触发退款结果的异步通知。退款结果的异步通知路径跟支付结果异步回调地址一致。退款回调参数中多refund_fee这个参数。退款回调参数如下：
